thought i would offer up some info on using stihl 2 cycle oil. i have heard a lot of people speak of using synthetic oil over the old red bottles. i was/am considering doing the same, but i stripper down my 90-r 4-mix weed eater because it was a little down on power and dealer had mention that the old regular oil has been known to carbon up the cylinder/valves etc. i have a 100+ hours on this weed eater, running for long periods at time. i pulled the piston/crank assenbly out of the cylinder and was shocked to see the chamber was spotless. valves/seats everything was spotless of carbon. only a 2 cycle mix coated everthing. cylinder was in great shape as well. there was no build up in the bottom half of the crank case. quite simply, the engine could not have looked in better shape.
i use fresh 93 octane in my engines and make sure its 1 gallon, no more , no less and then mix with right amount of oil.
don't get me wrong, i use synthetic oil in my 7.3 diesel, my wifes car, and my 501" big block. but these are reservoir systems that resuse the oil for a period of time. i suspect the synthetic oil can only help the small engines in chainsaws (and weedeaters), but i guess my point to this post is i don't think we are doing a disservice to our engines by using the old standby orange bottle oil.
what was wrong by the way. . . coil was to far away. how this happened, i don't know. i found this before splitting the case, but i has half way apart and wanted to see what the dealer was talking about. so i finished taking it apart anyway. put back together and all is well.
take this for what it is worth, one data point that says the regular oil still works.
